Abstract: ABSTRACT OF THE DISCLOSURE         In  the electrolytic refining of silver that contains a significant amount of copper, the electrolyte is withdrawn from the refining cell, preferably continuously but alternatively at intervals, and is contacted with an immiscible liquid phase containing a selective complexing agent for cupric ions.  The liquid phase carries away at least some copper from the electrolyte  without the need to remove the silver first.  The treated electrolyte, depleted of copper, is re-usable and is normally returned to the cell.  In a continuous-withdrawal system a steady copper level can be maintained in the electrolyte.  The complexing-agent phase can be regenerated and copper recovered from it.

Abstract: ABSTRACT OF THE DISCLOSURE      An exhaust brake valve assembly structurally arranged to provide reliable operation with relatively quick response.  The assembly includes a sliding gate valve member driven by a power actuator through a lost motion connection which generates a desir-able impact force on the gate to overcome static frictional forces.      The lost motion connection cooperates with a relief port in the gate to relieve peak pressure forces on the gate just prior to opening movement to additionally improve opening reliability and response.  Still further, the actuator includes a spring return arrangement in which the force rate adjacent the closed gate position is substantially greater than the force rate at the open position so that adequa?e reserve return force is developed for opening while only a minimal spring force resists piston movement in the initial opening movement.  A quick release valve is pro-vided on the actuator to rapidly exhaust fluid from the working chamber of the actuator to develop a high level of kinetic energy during the lost motion period.  The actuator is protected from extreme temperature by a heat barrier plate interposed between the valve housing and actuator.  A piston rod of the actuator is sealed by a radially floating seal and includes a reduced diameter portion and opposed shoulders for simple connection with the valve gate.

Abstract: IMPROVED SUBMINIATURE CONNECTOR ARRANGEMENT        ABSTRACT        An improved subminiature electrical connector arrangement especially suited for miniature electrical or electronic apparatus.  The connector arrangement includes a two-piece female connector assembly wherein one part thereof may be suit-ably interconnected to the circuitry of the apparatus while the same is outside the associated housing.  This connector may then be placed in alignment with an opening within the housing and a second connector portion inserts within the opening and makes a snap-fit, weather tight seal therein and engages said first connector portion, all without special tools or any additional hardware.  An associated male connector plug makes a convenient interconnection with the female assembly by including a hook-like projection overhanging one edge thereof and which engages a recess in the top of a housing to permit the male plug to rotate downwardly and inwardly into correct mechanical and electrical engagement with the female connector assembly.          The male plug further includes a plurality of contact spring elements with sidewardly extending projections which make wiping engagement with associated contact members in the female con-nector assembly and which exert a sidewise force therein so that, upon release of the associated fastening means securing the plug to the housing in its interconnected position, the sidewise spring bias forces the male plug at least partially out of the female assembly for an automatic disengagement and eject facility.

Abstract: ABSTRACT OF THE DISCLOSURE         Impact energy absorbing pipe restraints are provided which include a laminated strap for surrounding at least a portion of the circumference of a high energy pipe to restrain the movement of the high energy pipe in at least one direction during rupture.  The laminated strap is formed of a ductile material, i.e., one having the property of substantial elonga-tion in the plastic state, to absorb the impact energy of the ruptured pipe.  Advantageously, an elastic anchor means is affixed to the ends of the laminated strap to anchor the laminated strap about the high energy pipe and enable pivotal movement of the laminated strap relative to the high energy pipe to minimize any bending moment at the ends of the laminated strap, thereby minimizing any detraction in the allowable strain of the laminated strap.  Another form of impact energy absorbing restraint device includes a pipe positioned adjacent the high energy pipe and arranged substantially transverse to the longitudinal axis thereof to restrain the movement of the high energy pipe in at least one direction by absorbing the impact energy of the high energy pipe during rupture by crushing of the restraining pipe therewith.  Advantageously, crushing of the restraining pipe causes the ends of the restraining pipe to move upward so that in effect a well is formed by the restraining pipe which aids in the absorption of energy and restricts lateral movement of the ruptured high energy pipe.

Abstract: Abstract of the disclosure:    An improved and novel process has been found for the esterification of amino-benzoxazolone compounds containing a B-hydroxyethylsulfonyl group, by means of sulfuric acid or sulfur trioxide, with simultaneous or subsequent hydrolytic cleavage of the oxazolone ring, wherein the esterification and optional hydrolytic ring cleavage are performed in a machine which is operating with a kneading action and effect, using per mol of B-hydroxyethylsulfonyl compound 1 to 20 times the equivalent molar amount of concentrated sulfuric acid, oleum or sulfur trioxide.  This novel process has the great advantage that great amounts of sulfuric acid are saved which would con-taminate the waste-water, also in form of sodium sulfate  form-ed after the required neutralization.  Furthermore, the B-sul-fatoethylsulfonyl compounds formed as end-products in the esterification process are obtained in higher yields, in a higher esterification rate and in a higher purity.  They may be obtained in form of a powder or plastic mass, which is well transportable and storable, and can advantageously be used, if ring cleavage had taken place, without intermediate isolation of the pure sulfato compound itself, directly for the preparation of azo dyestuffs which are poor of inert salts, possess a high tinctorial strength and purity.
